I enjoy the speed and simplicity of chrome. For development work, I actually prefer the webkit DOM inspector to firebug. I was never a heavy plugin user to begin with, so firefox never tempted me much there. I think that if you're not planning on using plugins, the core browser features of chrome are more polished (again, this is just my opinion). If you're a heavy plugin user though, ff or opera is the way to go.
